| 摘 要： | 目的: 检测唾液腺恶性多形性腺瘤（malignant pleomorphic adenoma,MPA）中人上皮生长因子受体2（human epithelial growth factor receptor 2,HER2）蛋白表达、基因扩增情况,分析其与肿瘤临床病理及患者预后的相关性,以期评估其作为靶向治疗位点的可能性。方法: 应用免疫组织化学染色法检测140例MPA患者肿瘤组织中HER2蛋白的表达,对HER2基因扩增情况不明确者（HER2 2+）行荧光原位杂交,确定基因扩增状态。统计140例患者临床病理资料并进行随访,应用SPSS16.0软件包中的Kaplan-Meier、Cox比例风险模型,分析HER2基因扩增与MPA肿瘤临床病理及患者预后的相关性。结果: 140例MPA患者中,HER2阳性率为25%。腺癌亚型MPA中,HER2阳性率达到40.5%（32/79）,显著高于肌上皮癌亚型MPA（4.9%,3/61）（P<0.05）。HER2阳性与肿瘤患者性别、组织学分级及N分期显著相关。生存分析显示,HER2阳性患者总生存率及疾病别生存率低。结论: HER2基因过表达及扩增与MPA肿瘤细胞恶变亚型显著相关,并且提示MPA患者较差的预后状态。 |

| Abstract: | PURPOSE: To investigate HER2 gene overexpression or amplification in human salivary malignant pleomorphic adenoma (MPA), and analyze the association between HER2 and tumor clinicopathological characteristics, as well as prognosis, in order to assess its potential as a therapeutic target. METHODS: The expression of HER2 protein was detected by immunohistochemistry in 140 patients with MPA, and the amplification of HER2 gene was determined by fluorescence in situ hybridization for HER2 2+ cases. The clinicopathological data of 140 patients were reviewed. The correlation between HER2 gene amplification and clinicopathological features and prognosis of MPA patients was analyzed using SPSS 16.0 software package. RESULTS: The positive rate of HER2 in 140 patients with MPA was 25%. The positive rate of HER2 in adenocarcinoma subtype of MPA was 40.5% (32/79), which was significantly higher than that of myoepithelial carcinoma subtype MPA (4.9%, 3/61, P<0.05). HER2 positive staining was significantly correlated with gender, histological grade and N stage. Survival analysis showed that overall survival and disease-specific survival were lower in HER2 positive patients. CONCLUSION: Overexpression and amplification of HER2 gene is significantly correlated with the malignant subtype of MPA tumor cells, and suggests a poor prognosis in patients with MPA. |
